Description

(54) осЕрадиАльный ДИФФУЗОР выхлопного(54) AFTER DIFFUSER Exhaust

ПАТРУБКА ТУРВОМАШИНЫNOZZLE TURVO MACHINE

етс  перепадом давлений на вогнутой и выпуклой поверхност х ребра.The differential pressure on the concave and convex surfaces of the ribs.

Предлагаемое выполнение осерадиального диффузора позвол ет устранить или уменьшить прот женность зон отрывного течени  потока в его проточной части, увеличить эффективность восстановлени  давлени  и, тем самым, уменьшить гидравлические потери.The proposed implementation of an aseradial diffuser makes it possible to eliminate or reduce the length of the separated flow zones in its flow part, to increase the efficiency of pressure recovery and, thereby, to reduce hydraulic losses.
